// CLASS DESCRIPTION (MPxGeometryIterator)
|
|
//
|
|
// This is the base class for user defined geometry iterators.
|
|
// Geometry iterator allow iterating over components in geometry
|
|
// in a geometry independent manner. This base class defines
|
|
// the interface to be used maya when a generic component iteration
|
|
// is required.
|
|
//
|
|
// This class is used in conjunction with MPxSurfaceShape to provide
|
|
// an iterator for components in a user defined shape.
|
|
// The main methods to override in this class are point and set point.
|
|
// The reset, isDone, and next methods have a default implementation
|
|
// and should only be overridden if the component being iterator on
|
|
// is not a single indexed component type.
|
|
